3 3. Способ по п. 1, отличающийс тем, что при переходе с низкого напр жени на высокое осуществл ют пересоединение обмоток электродвигател со схемы разомкнутого треугольника на схему с носледовательно-па-5 раллельным включением и пересоединение 4 фазосдвигающих элементов с параллельного соединени на соединение, при котором одна часть фазосдвигающих элементов подключена параллельно, а друга часть - последовательно соответствующим обмоткам электродвигател .3 3. The method according to claim 1, characterized in that when switching from low voltage to high voltage, the motor windings are reconnected from an open triangle to a circuit with a successive-pa-5 parallel connection and re-connected 4 phase-shifting elements from a parallel connection to a connection in which one part of the phase-shifting elements is connected in parallel, and the other part - in series with the corresponding windings of the electric motor.

DEVICE FOR CAPACITORS OF THE NON motor terminals. This is achieved due to the fact that an additional current source is used as a direct current source. capacitors connected in series with valves between each 2 phase of the motor and a limiting resistor connected to the zero point of the stator winding. The figure shows the electrical circuit of the device described. 25 The device consists of capacitors connected to the winding / stator 2 connected between each phase of the stator and the current limiting resistor 3 connected to the zero zone.
